Hello,
I have an older JD f725 mower with a little problem. It runs great for 20 min. or a half hour, then it starts to die like it is out of gas. If I choke it and turn off the deck, I can usually make it back to the shed. If I let it cool down for a couple of hours, I can go mow for another 20 min. New fuel filter didn"t help. I took off the carb and cleaned out the float bowl and squirted carb cleaner every place I could without taking the whole thing apart. That didn"t help either. I thought maybe the fuel pump was not working properly. It works great when I opperate it by hand, could engine heat cause the fuel pump to not work? Am I missing something else obvious?
